Site to site VPN and MTU

Site to site VPN and MTU
So I was reading about how having a MTU size of 1500 on devices communicating across a site to site VPN can be inefficient. The packets often have to be fragmented once they reach the VPN gateway due to the additional data.
I've been thinking about putting a protocol analyzer on both sides of the vpn gateway to see how the traffic is affected.
Does anyone have any thoughts/experience about tweaking MTU size on hosts to optimize VPN traffic?




What is a VPN?

VPNs (Virtual Private Networks) were first used by companies to enable their employees to securely access internal systems such as email remotely (e.g. from home or while on business trips). Today they are increasingly being used for personal use by individuals to protect their privacy while online in public places (e.g. when using the wi-fi connection in a cafe) or in a country where the internet is censored / blocked (e.g. China, Saudi Arabia).

Why do I need a VPN?

Whether youre an expat living in a foreign country where the internet is heavily regulated, a mobile user constantly on the road, or just someone concerned with maintaining their privacy online, having aVPNis becoming essential.
